Hydroxyapatite can be divided into: toothpaste grade hydroxyapatite, food grade hydroxyapatite, special ceramic grade hydroxyapatite, fluoride removal adsorption grade hydroxyapatite, suspension polymerization dispersion grade hydroxyapatite

 

Toothpaste grade hydroxyapatite has the functions of preventing caries, removing dental plaque and stains, repairing whitening enamel, relieving allergy, etc. Adsorption, bacteriostasis, remineralization, anti sensitivity, and whitening are the main effects of hydroxyapatite used in toothpastes. More importantly, hydroxyapatite has biocompatibility and can repair enamel. The repair rate of shell hydroxyapatite is 32%, and the repair rate of artificial hydroxyapatite is 85%, The repair effect is obviously higher than that of shellfish.

 

1. Antibacterial activity: Hydroxyapatite has good antibacterial activity. It is compounded with corresponding cosmetics, toothpastes, etc. to make corresponding antibacterial toothpaste, shampoo, lipstick, skin cream, etc., so that the product can not only have antibacterial durability, but also deodorize. Therefore, using hydroxyapatite particles as adsorbent to adsorb and remove oral harmful bacteria will play an important role in preventing dental caries.

 

2. Anti sensitivity: Hydroxyapatite is the main inorganic component of human bone and teeth, safe and non-toxic, and has a high affinity with enamel. It can repair the tiny cracks on the surface of teeth and dentin, so that a dense mineralized layer can be generated on the surface of teeth, showing a good potential of natural sealing of dentin tubules and anti dentin hypersensitivity. It has become a research hotspot of anti sensitive active ingredients.

 

3. Whitening: Hydroxyapatite is a soft material with high whiteness and Mohs hardness of 5.8. It can be used alone as a toothpaste friction agent or in combination with other friction agents. Its products can not only play a good role in friction and polishing, but also can eliminate stains and tartar, and have excellent tooth whitening performance.

 

Hydroxyapatite is the main component of human bones and teeth. 65% of human bones, 70% of dentin, and 95% of enamel are all hydroxyapatite, with the total content reaching 20% of the human body. Characteristics of hydroxyapatite: white, tasteless, safe and edible; Small particle size, large surface area; Strong biological activity, Mohs hardness 5.8, excellent friction characteristics; It has strong combination with pigment, strong ability to absorb bacteria, significant anti-inflammatory and hemostatic effects, strong ability to inhibit harmful bacteria, strong biocompatibility, and strong anti caries function.

Hydroxyapatite toothpaste can not only clean teeth with ordinary toothpaste, but also repair cracks and holes in teeth, thus strengthening the tooth surface. The hydroxyapatite used in the tooth filling toothpaste has a strong affinity with saliva. After brushing with this toothpaste, the hydroxyapatite powder quickly combines with the enamel under the action of acidic components in saliva, thus playing a role in repairing and strengthening the enamel. Long term use shows that hydroxyapatite toothpaste has the functions of preventing caries, removing dental plaque and stains, repairing whitening enamel, and relieving allergy.

 

Sichuan Mianyang Xingheyi New Material Technology Co., Ltd. was established on April 12, 2018, and its registered place is located in Wangchong Street, Yongchang Town, Beichuan Qiang Autonomous County. Its business scope includes the research, development, manufacturing, promotion, application and sales of new material hydroxyapatite and related calcium products, and powder processing products.
